How old are you really? – What is your biological age? How Is It Different Than Your Normal Age, and Why Is It Important?

Reading time: < 7 min

You’ve met someone who looks younger or older than their age, right? What this should tell you is that we all age differently. Some people age faster, and some age gradually. You will find a 40-year-old who doesn’t seem to be in their 40s. And a 70-year-old who seems to be 50 and is fit to do some things that the 40-year-old can’t. 

This difference in how we age can be explained by the fact that everybody has two ages; biological and chronological age. 

What Is the Biological Age?

Your biological age is how you seem, your physical appearance. The biological age is the explanation behind the mystery that some people look younger and others older than their real age. It is also referred to as physiological age.

The rate at which we age is not something we can control because it greatly depends on our genetics. However, studies show that there are a couple of external factors that contribute to how we age. These factors include nutrition, exercise, smoking and smoking. 

Though how you age is greatly influenced by your genetics and your real age, your lifestyle also counts in how young or old you appear to be. As much as we can’t choose our genetics, we have control over our lifestyle. Eat healthy diets, get enough sleep and exercise regularly.

What’s The Difference?

You’re probably still wondering what the difference is between biological and chronological age. That’s probably because you didn’t know that humans have two ages. We’ll explore the difference in this section.

The chronological age is what you have always known to be your age. It is the time in years and months since you were born. Let’s say you were born in September 2000; as of September 2022, your chronological age is 22 years. So, when celebrating your birthday next time, remember that it is only your chronological age that has increased.

Biological age, which we’ve said is the age you seem to be, takes into account more than just the time you’ve been alive. It is an indication of your lifestyle despite your age. Someone who exercises regularly, has proper nutrition, maintains a healthy and consistent sleep routine and doesn’t smoke is highly likely to look younger than somebody else of the same age but with an unhealthy lifestyle.

Chronological age increases at the same rate for everybody. We all turn a year older every year on our birthday. But the rate at which our biological age increases is different for everybody. This is due to the fact that our body cells deteriorate at different rates depending on lifestyle and genes.

As a result, biological age is a major risk factor for most chronic diseases such as diabetes and heart disease. Although some of these diseases are associated with old age (chronological age), the age at which one gets these diseases varies.

So, how is this biological age determined? Scientists have come up with different methods to determine the biological age. One such method used in determining the biological method is by identifying and observing a variety of biomarkers. Research over the years shows that cellular biomarkers are effective in foreseeing some health conditions years before they develop.

The Epigenetic Clock

The epigenetic clock is one of the most accurate methods of estimating the biological age of an individual. The epigenetic clock determines biological age by observing a particular biomarker known as DNA methylation.

DNA methylation is the chemical modification of the DNA by adding a methyl group to the 5th carbon molecule. However, DNA methylation doesn’t change the DNA sequence. DNA methylation regulates the genes to be turned off or on in a particular cell. So, the cells will have the same DNA but different genes.

Scientists and doctors observe different patterns of DNA methylation across different body cells. These patterns change as you age. There are some genomes where the methylation increases and others where it decreases as you age. So, doctors monitor these patterns from different genomes associated with aging and overall body functioning to determine your biological age.

Implications of Knowing Your Biological Age

You’re probably wondering why you should know your biological age. Knowing your biological age is the only control that you have over how you age and what age your physical appearance says about your age. It will help you take the necessary steps for your well-being.

Knowing your biological age will give you a chance to live a healthy life and look and feel years younger. Lifestyle has a lot of influence on your biological health. Fortunately, this age can be improved, unlike the chronological age. All you have to do is change your lifestyle and adopt healthy habits. Start exercising, have a balanced nutrition plan, get enough sleep and avoid stress and smoking.

Observing cellular biomarkers can identify changes in the cells years before any health conditions start developing. This degeneration in cells is what causes most of the chronic conditions associated with late life. So knowing about what might cause a certain condition a decade before can help you take some measures to prevent it or derail the process. 

Determining Your Bioage Using the Epigenetic Age Test

The good news for those who are afraid of needles is that you can measure your biological age without drawing any blood. Thanks to research and innovation, companies have developed at-home testing kits. These kits use saliva to determine your biological age.

When saliva samples are put in the testing kit, epigenetic data is generated. This data is then used to calculate your biological age. Saliva and blood have many cell types that are the same. Therefore, the biological age obtained from saliva is similar to that from the blood.
